Hello, this is Fabian, I've been assigned to support your case.
Thank you for your interest in our products.
As you may have noticed, we don't have any example that can be referred to in order to use PN722x for a proper polling of Felica cards. PN7220 does support Felica cards and, the configurations can be seen in section 19 Annex C: RF protocol configuration indexes.
These configurations can be done by using our GUI: NFC Cockpit. But, the implementation for loading the configurations in your own application must be done by the respective development team.
Additionally, the use of PN7160 examples as a reference for building the NCI commands will be very useful for your application. This IC also uses NCI 2.0 as well meaning that the commands will be quite similar. Still, is recommended to use Cockpit and, address the PN722x datasheet.
Best Regards,
Fabian
